I've had this Sceptre lcd monitor for a little over a year now. Within the last few months, a film of dirt (or something) is slowly creeping on the edges of the screen. I wash the screen on the outside correctly (nothing sprayed directly onto it, proper solutions used,etc) and it does nothing. Smoking by others near it is kept to a minimum, but I worry maybe that's it. It seems to be on the inside of the screen cover.
I can see through it. It is not dead pixels, or lighting issues from behind.
So the problem becomes, barring having someone open it up, is there anyway to clean it? If it has to be opened up, anyway it can be done without having to shell out a bunch of money? Or is the monitor a lost cause?

Re: Dirt? on edge of screen
Don't be afraid of cleaning the screen...it's won't bites or give you a heart attack. Hehehe... To cleaned the edges just use a Q'tip dip it to a tap water and gently cleaned it...If necessary removed the bezel. After that you can cleaned the whole screen with a damp soft paper towel... So, give a tried....:)

Probably not. This is most likely either a backlight going out, or an inverter board going bad, or other internal component (costs $100+ to replace by a professional). Not worth it to fix in most cases, unless you have an extended warranty, or a local repair shop with really good rates.
However, you can try another monitor cord (between monitor and computer; not likely to be the problem, but rarely can help). Flat screen (monitors/TVs/laptops) generally last 5+ years with average use, but I've seen them fail within 2 years (especially on laptop computers). In general, if you got 3 to 5 years out of a monitor, you did ok.
PS: If buying a new LCD monitor or TV, look for one that says "LED" on the box. (LCD monitors traditionally had a few fluorescent bulbs inside as "backlights", but newer LCD monitors/TVs have hundreds of tiny LED lights inside, which last longer, use slightly less electricity, and give more even lighting on the screen edges).
This could be as simple as the video cable isn't connecting securely. You could try replacing the cable or screwing it tighter. We recently had a red tint on an external monitor for a laptop because the cable was loose; since the laptop moved regularly, screwing the connector to the port on the machine wasn't a convenient solution. The other reasons for an odd tint like that is the video card or the monitor starting to fail. Attaching the monitor to a different computer and seeing if the problem repeats will check if it is the monitor and not the video of the computer.
Have you tried any other monitor connected to your computer since your current problem? Check your connections, make sure your VGA cable/DVI cable are in good condition. If none of that works try to RMA it to sceptre if your still within the 1 year period.
Something has failed or is failing in the monitor. It may be serviceable, but may not be cost effective to do so unless something has just come loose. I'm assuming you have no problems with the new monitor. Your time line is a little confusing.
I am working on one of these for a customer. Found leaky cap on 5 volt power supply. replaced it, still no backlight. Looked at the inverter with an o-scope and it runs for a few seconds then shuts off. I hooked a ccfl across each of the transformer secondaries on the inverter and it lit up! I believe the problem is failed ccfl units. There is plenty of voltage there to light them up, I have an rf burn on my thumb to show for it. I have not looked at the ease of dis-assembly of the display to replace the backlights. It does not look easy.
Just fixed mine. Maybe it's a few years late. Hope you guys still have the display. It's the power supply board. I've just replaced 4 bulge capacitors near one edge of the PS. They are 2x1000uF 10V, 1x470uF 25V & 1x470 10V. I salvaged my parts from an old CRT monitor. Hey you can go green with your repairs too!
From the sounds of your problem, you have a few dead pixels. This is a problem that can exist in LCD displays that have not been quality tested or have been damaged in some other way. If the unit is still under warranty, I would see if it could be exchanged for another monitor. Short of replacing the LCD screen, you would only be left with the option of living with the aggravation.
P.S. The main reason you couldn't get the monitor apart is due to the fact that there are plastic clips mated with indentations in the other half of the housing that must be released before it will seperate. They are about every 4 inches around the entire seam of the two halves.
Hope this helps.
